Once formed, a bud may remain for some time in a dormant condition, or it may form a shoot immediately. Buds may be specialized to develop flowers or short shoots or may have the potential for general shoot development. The term bud is also used in zoology, where it refers to an outgrowth from the body which can develop into a new individual.
The edible portion of the plant consists of the flower buds before the flowers come into bloom. The budding artichoke flower-head is a cluster of many budding small flowers (an inflorescence), together with many bracts, on an edible base. Once the buds bloom, the structure changes to a coarse, barely edible form.
The flower buds are arranged in leaf axils in groups of three on an unbanched peduncle, the individual buds sessile or an pedicels up to 4 mm (0.16 in) long. Mature buds are oval to spindle-shaped, 5–9 mm (0.20–0.35 in) long and 3–5 mm (0.12–0.20 in) wide with a conical to rounded operculum. Flowering mainly occurs from December to ...

The flower buds initially have a pale hue, gradually turn green, then transition to a bright red when ready for harvest. Cloves are harvested at 1.5–2 centimetres ( 5 ⁄ 8 – 3 ⁄ 4 in) long, and consist of a long calyx that terminates in four spreading sepals , and four unopened petals that form a small central ball.
The adventitious buds help to replace lost branches. Adventitious buds and shoots also may develop on mature tree trunks when a shaded trunk is exposed to bright sunlight because surrounding trees are cut down. Redwood (Sequoia sempervirens) trees often develop many adventitious buds on their lower trunks. If the main trunk dies, a new one ...
In a bud or flower bud, the relative arrangement of the sepals or petals of each flower whorl is called vernation. This arrangement must be observed in the flower bud because in the fully open flower the floral parts are often so far separated from each other that the vernation cannot be determined. There are six main types of vernation.
Latent bud – an axillary bud whose development is inhibited, sometimes for many years, due to the influence of apical and other buds. Also known as a dormant bud. Leaf bud – a bud that produces a leafy shoot. Mixed – buds that have both embryonic flowers and leaves. Naked – Pseudoterminal – Reproductive – buds with embryonic flowers ...
